kepian danian lieutenant ability

alright so i had the bright idea to instead of using only 4 tribes why not use 6, ( possibly 5 thats what im getting at) but part of those 6 i had in mind was the "tribeless" and m'arrillians. Now i know that m'arrillians would count but now im questioning whether or not tribeless would, i've read a few posts that tribeless can not be placed in loyal decks which would insinuate that they are there own tribe, but i just want to make sure they do being that i hate using creatures when i dont fully understand their ability.

Many decks have implemented 5 tribe unity to get the most out of effects like kepiann unfortunately 5 is as high as you can go. As there name suggests tribeless creatures have no tribe (note how on the card types bellow the picture no tribe is listed). They can gain a tribe with an effect like generals standard but they themselves are not a type of tribe but rather a lack of tribe.
